A car is travelling at an average speed of 60 km per hour. How much distance will it cover in 1 hour 12 minutes?

Options

A. `50 km`
B. `72 km`
C. `63 km`
D. `67.2 km`

Answer

To solve the problem step by step, we will determine how much distance a car traveling at an average speed of 60 km per hour will cover in 1 hour and 12 minutes.

### Step 1: Convert the time into hours
1 hour and 12 minutes can be converted into hours.
- Since 1 hour is already in hours, we just need to convert 12 minutes into hours.
- There are 60 minutes in an hour, so:
\[ 12 \text{ minutes} = \frac{12}{60} \text{ hours} = 0.2 \text{ hours} \]
- Therefore, the total time in hours is:
\[ 1 \text{ hour} + 0.2 \text{ hours} = 1.2 \text{ hours} \]

### Step 2: Use the formula for distance
The formula for distance is given by:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
- We know the speed of the car is 60 km/h and the time is 1.2 hours.

### Step 3: Calculate the distance
Now, we can substitute the values into the formula:
\[ \text{Distance} = 60 \text{ km/h} \times 1.2 \text{ hours} \]
- Performing the multiplication:
\[ \text{Distance} = 72 \text{ km} \]

### Conclusion
The car will cover a distance of **72 kilometers** in 1 hour and 12 minutes.
